Introduction. Senegal produces up to 150,000 t of fruit, of which 60,000 t are mangoes. Fruit production is important for the Niayes region, where 60% of total production is of mangoes, with citrus production coming next at 24%. Mango losses have become more substantial since the arrival of Bactr...

Desde la introducción de Thrips palmi Karny a Colombia, éste se convirtió en una de las principales plagas de la habichuela en el Valle del Cauca y es hoy objeto de excesivo uso de insecticidas para su control. Una de las formas de racionalizar el uso de insecticidas es hacer las aplicaciones en ...

Thrips palmi Karny es una plaga de habichuela y fríjol en Colombia, detectada en 1997 en el Valle del Cauca, que ocasiona grandes pérdidas económicas en estos cultivos. Con el Tin de conocer la dispersión del insecto en la planta, cómo se desarrolla la población a través del ciclo del cultivo, el...

Natural entomopathogenic nematodes (EPNs) are considered as potential biological control agents against soil-borne insect pests. This study was conducted to determine the impact of land use on the distribution, occurrence and diversity of entomopathogenic nematode community. Isolation of EPNs was...

Density-specific sampling plans were developed under African conditions for the exotic spider mite, Mononychellus tanajoa (Bondar), a serious pest of cassava, Manihot esculenta. The within-plant distribution of Mononychellus tanajoa was found to favour new foliage, regardless of time of planting ...

Soil data requirements and soil data acquisition tools and techniques have changed over recent decades. In general, soil scientists can: i) collect new data in the field and ignore the data that are available, ii) rely entirely on legacy soil data or iii) combine available legacy data with new da...
